  skos:definition """A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a special symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. Constants arise in many areas of mathematics, with constants such as <span class="texhtml mvar" style="font-style:italic;">e</span> and <span class="texhtml mvar" style="font-style:italic;">π</span> occurring in such diverse contexts as geometry, number theory, statistics, and calculus.
